Hi, I'm trying to load MarsSession dynamically by instantiating a prefab that holds it + all other references. So far I've succeeded but I have 2 issues: 1. I can't change the world scale parameter from the prefab scene - im getting error that tells me that current scene does not contain mars session (see image) 2. I have memory leaks when i'm unloading the mars session (by simply destroying it), I don't see the memory get clean and it always rising when i'm instantiating the mars session again. I'm also get memory leaks when im unloading the scene and not just destroying the prefab. I'm of course making to clean all the references and resources. What i'm doing wrong? is MarsSession designed to be part of a scene and not part of a prefab? I shouldn't instantiate it? I didn't see anything about it in the documents. Thanks, Udi.
